I always find myself defending the semi-auto Uzi. I purchased a Vector 9mm Uzi several years ago and made it an SBR (engraved the barrel). At the time I contemplated going the FA route because everyone always says an Uzi is worthless unless it is Full Auto. However, once I tuned out what everyone else was saying and started just thinking about it myself for my application it became an easy choice. For me a Full Auto Uzi would be almost useless. I use my Uzi on my little farm all the time. I keep it handy when working, on hikes, and hunting. (yes, I hunt with an Uzi; mostly coyotes but it is now legal to hunt deer with any centerfire in my state and there is no magazine limit so I am excited about taking my first deer with my Uzi soon). In the state the I live, it is not legal to hunt with a full auto so if I had gone the full auto route my usage of it would have been relegated to mostly just fun range time. I really love carrying my Uzi with me and actually using it on my hikes and hunts but I would not have been able to do so legally with a FA Uzi.
The other main reason for me choosing to go the semi-auto route is because it has a closed bolt. I understand the advantage of open bolt if you are shooting full auto; but I have never liked open bolt. It will be less accurate and more prone to getting debris in the action when working, hiking, climbing, etc. Mostly it was due to accuracy. Even if I had a full auto Uzi and laws changed and I was able to use it legally for all of my activities; I would still be taking most of the important shots in semi mode and would prefer the more accurate closed bolt. So after actually thinking it through it became apparent to me that full auto provided advantages that I would seldom need or use and the semi-auto option provided advantages that would make the Uzi vastly more useful and versatile for me. The only advantage I see for the full auto Uzi would be for suppressing fire which I have yet to see a use for on my farm
The last consideration was the obvious one; the cost. The full auto would have cost 6-7 times as much as I paid for my semi. I was willing to pay that price at the time, as long as it made sense. It just did not make sense to me to pay that much more for something that would actually be less useful for me. As it is, my Uzi is my go-to gun when I go for a hike, walk, or am working around the farm cutting brush, making paths, etc. It has killed many snakes and critters.
